Because Bluet

18、ooth technology can be easily embedded into a single chip, so it is especially suitable for small mobile communication devices.Bluetooth carrier frequency used globally 2. 4GHz ISM industrial, scientific, medical) band, the 2. 4GHz ISM band is open to all radio frequency systems, the use of any one

19、frequency band are likely to encounter unpredictable Sources of interference. Using frequency hopping spread spectrum technology is an effective measure to avoid interference. Band frequency hopping is to be divided into a number of frequency hopping channels in a connection, the radio transceiver a

20、ccording to a certain code sequence and continuously from one channel to another channel, the two sides is the only transceiver to communicate according to the law, while others Sources of interference can not be carried out by the same laws of interference. Instantaneous bandwidth of frequency hopp

21、ing is very narrow, but through spread spectrum technology to make this into a narrow bandwidth to expand into broadband times, so that the impact of interference may become very small. Bluetooth uses frequency hopping spread spectrum technology is one of the key. Corresponds to the single-slot pack

22、et, the Bluetooth frequency hopping rate of 1600 hop / sec; corresponding slot bag, hopping rate is reduced; in 3200 to establish the link to raise the jump / sec. Such a high rate of use of frequency hopping, Bluetooth system has a sufficiently high anti-interference ability. It uses the butterfly

23、as the core of multi-level mapping program, compared with other programs, with a hardware device is simple, superior performance, ease of 79/23 band compatible with the two systems and a variety of state hopping sequence using the same circuit to realize.The human voice is the most basic and direct

24、exchange of information. Since the phone has been invented, voice communication has always been to continue the development of fast rate from the previously adopted a comprehensive approach to digital simulation methods. Digital voice signal transmission and storage reliability, interference immunit

25、y, security and price and so on are much better than analog voice signal. Voice to digital format are often stored and transmitted, the data can be transmitted through voice devices. Some wireless communication technology is designed to transmit voice, while others are designed for use with data ser

26、vices. The Bluetooth technology supports both voice and data transmission, can support voice or data devices to communicate with each other. Contribute to the development of the system's wireless voice message listener. More spiritual system works if either the wireless remote control PC, and up

27、load the voice data collected microcontroller can also choose to operate the system locally. The two control not only independent of each other, can be used alone, but also cross-use with each other to meet the practical requirements of different jobs. As the system uses Bluetooth wireless communica

28、tion, the transmission speed, high reliability, not only to ensure that the voice listener, but also to make itself has some anti-detectable. In addition, the MCU side joined the U disk function of large-capacity data storage can be necessary in the circumstances to save the information locally and

29、temporarily sent outside until the right time to further transmission. This undoubtedly increased the hidden nature of the whole system to make it closer to the practicability. 藍(lán) 牙人類正步入數(shù)字化網(wǎng)絡(luò)信息時(shí)代，目前很多數(shù)字通信和數(shù)據(jù)傳輸都是通過纜線連接來實(shí)現(xiàn)的。這些纜線通過各式各樣的連接器與各式各樣的設(shè)備相連接，這些連接器要在形狀、尺寸及引腳數(shù)目上相匹配。數(shù)字化設(shè)備的有線連接給人們隨時(shí)隨地與信息網(wǎng)絡(luò)連接和通信帶來了許

30、多不便。發(fā)展無線通信連接技術(shù)，將人們從有線連接的束縛中解放出來，已經(jīng)成為一種趨勢(shì)。信息時(shí)代最大的特點(diǎn)便是更加方便快速的信息傳播，正是基于這一點(diǎn)技術(shù)人員也在努力開發(fā)更加出色的信息數(shù)據(jù)傳輸方式。藍(lán)牙技術(shù)(Bluetooth)是1998年由愛立信(Ericsson)、諾基亞(NOKIA)、東芝(TOSHIBA)、美國國際商用機(jī)器(IBM)和英特爾(INTEL)等公司聯(lián)合推出的一種開放性短距離無線通信技術(shù)。旨在用于替代便攜或固定電子設(shè)備上使用的電纜或連線等有線連接。其主要特點(diǎn)在于功能強(qiáng)大、耗電量低、傳輸可靠性高、通用性強(qiáng)、成本低廉、簡單易用。在辦公室、家庭、旅途和實(shí)驗(yàn)室中，無需在任何電子設(shè)備間布設(shè)專用

31、線纜和連接器。通過藍(lán)牙裝置可以組成一個(gè)“微網(wǎng)”，網(wǎng)內(nèi)任何藍(lán)牙收發(fā)器都可與該裝置互通信號(hào)，而且這種連接無需復(fù)雜的軟件支持。拋開傳統(tǒng)連線的束縛，徹底地享受無拘無束的樂趣，藍(lán)牙給予我們的承諾足以讓人精神振奮。藍(lán)牙，對(duì)于整個(gè) IT 產(chǎn)業(yè)而言，已經(jīng)不僅僅是一項(xiàng)簡單的技術(shù)，而成為了一種概念。 藍(lán)牙技術(shù)的創(chuàng)始人是瑞典的愛立信公司，其早在1994年即已進(jìn)行研發(fā)。1998年 2 月，愛立信、諾基亞、IBM、東芝以及 Intel 五家跨國公司組成了一個(gè)特殊興趣小組(SIG，Special Interest Group)，旨在建立一個(gè)全球通用的短距離無線通訊技術(shù)標(biāo)準(zhǔn)，即現(xiàn)在的藍(lán)牙技術(shù)。藍(lán)牙的名字來源于 10 世紀(jì)丹

32、麥國王 Harald Blatand英譯為 Harold Bluetooth(因?yàn)樗窒矚g吃藍(lán)莓,所以牙齒每天都帶著藍(lán)色)，他在歐洲曾經(jīng)統(tǒng)一過挪威、瑞典和丹麥。將這項(xiàng)高新技術(shù)以他的名字來命名，是為表達(dá)藍(lán)牙技術(shù)要統(tǒng)一行業(yè)標(biāo)準(zhǔn)，使不同工業(yè)領(lǐng)域間協(xié)調(diào)工作、彼此能夠良好交流之意。藍(lán)牙技術(shù)工作在無需申請(qǐng)?jiān)S可證的2.4GHz的ISM頻段上，基于時(shí)分復(fù)用和跳頻原理，將電路交換和分組交換結(jié)合，適合于語音傳輸和數(shù)據(jù)傳輸。目前，藍(lán)牙產(chǎn)品已廣泛被應(yīng)用于移動(dòng)通信、計(jì)算機(jī)及其周邊設(shè)備、汽車、工業(yè)控制、家電設(shè)備、辦公應(yīng)用、電子商務(wù)、醫(yī)療健身等多個(gè)領(lǐng)域。藍(lán)牙技術(shù)使各種移動(dòng)設(shè)備、計(jì)算機(jī)外設(shè)等數(shù)字設(shè)備之間的無線廉價(jià)連接成為可

33、能，它不僅取代了這些設(shè)備之間的纜線連接，而且還使得許多數(shù)字設(shè)備的功能得到了擴(kuò)充，讓原來獨(dú)立的數(shù)字設(shè)備可以與其他設(shè)備連網(wǎng)交換信息。由于藍(lán)牙體積小、功耗低，幾乎可以被集成到任何數(shù)字設(shè)備中，特別是那些對(duì)數(shù)據(jù)傳輸速率要求不高的移動(dòng)設(shè)備和便攜設(shè)備。人們提出了許多應(yīng)用設(shè)想，有些己經(jīng)有產(chǎn)品問世。從市場的角度看，藍(lán)牙技術(shù)可制造出點(diǎn)對(duì)點(diǎn)連接、點(diǎn)對(duì)多點(diǎn)連接的應(yīng)用產(chǎn)品以及個(gè)人局域網(wǎng)等網(wǎng)絡(luò)產(chǎn)品。越來越多的人考慮給自己的設(shè)備增加無線連接，人們也逐步意識(shí)到藍(lán)牙技術(shù)的低功耗和低成本解決方案是理想的。SIG為了推廣藍(lán)牙技術(shù)的使用，將藍(lán)牙的技術(shù)標(biāo)準(zhǔn)全部公開，全世界范圍內(nèi)的任何單位和個(gè)人都可以進(jìn)行藍(lán)牙產(chǎn)品的開發(fā)，只要最終通過SIG的藍(lán)牙產(chǎn)品兼容性測試，就可以推向市場。目前許多制造商已紛紛制造藍(lán)牙產(chǎn)品，未來的藍(lán)牙技
